Solution Overview

Problem

Conventional card payment systems are inconvenient as they require physical cards, expose financial information, increase the risk of fraud, and make it difficult for customers to select optimal payment methods that utilize bonus information such as discounts, membership points, and coupons.

Innovation Solution

A complex payment system using a portable terminal that executes an e-wallet program, allowing payment information to be transmitted to a vendor server for analysis with bonus information like coupon, discount, and membership point data to determine optimal payment conditions, enabling secure and economical transactions without physical cards.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional card payment methods are used, then payment can be made at affiliated shops, but physical cards are required and financial information may be exposed

Engineering Contradiction:

Improvepayment securityVSAvoidfinancial information exposure

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent uses virtual copies of payment cards stored in the portable terminal's memory instead of physical cards. The card information is copied into the terminal and used for contactless payment transactions, eliminating the need to physically handle or expose actual card details while maintaining payment functionality.

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The portable terminal acts as an intermediary device between the payment system and the user's financial information. Instead of directly exposing card details to merchants or payment systems, the terminal mediates the transaction using stored virtual card data and communicates only necessary transaction information, protecting the user's financial data.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If conventional card payment systems are used, then transactions can be processed, but the risk of fraud and illegal reproduction of card information increases

Engineering Contradiction:

Improvetransaction processingVSAvoidfraud risk

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

By storing virtual copies of card information in the portable terminal rather than using physical cards, the system enables rapid transaction processing while eliminating the risk of physical card theft or illegal reproduction. The virtual card data in the secure terminal cannot be physically replicated.

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The patent replaces the mechanical physical card system with an electronic data storage and transmission system. Instead of physically handling cards that can be stolen or copied, the system uses electronic verification through the portable terminal, substituting physical security mechanisms with cryptographic and database-based security.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If customers use conventional payment methods, then payment can be made, but it is difficult to select optimal payment methods that utilize bonus information

Engineering Contradiction:

Improvepayment convenienceVSAvoidbonus information utilization

Core Design Contradiction:

Ease of operationVSLoss of information

Solution Approach 1:

The portable terminal automatically queries the server about available bonus information (discounts, coupons, membership points) related to the payment and receives feedback. The terminal then presents multiple payment options with different bonus benefits to the user, enabling informed selection of the optimal payment method that maximizes bonus utilization.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The portable terminal serves multiple functions: it stores various types of card information, queries bonus information from servers, calculates optimal payment methods considering different bonuses, and executes transactions. This multi-functionality consolidates what would otherwise require multiple separate systems into a single device.

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Reliability

If card information is transmitted through VAN providers and card terminals, then payment approval can be obtained, but the complexity of the payment system increases

Engineering Contradiction:

Improvepayment approvalVSAvoidpayment system structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple functions into the portable terminal: card storage, server communication, bonus calculation, and transaction execution. The server also merges card information storage, bonus information management, and optimal payment calculation into a single system, simplifying the overall architecture compared to separate specialized systems.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

Disclosed are a complex payment system using a portable terminal, and a complex payment method. According to the present invention, a portable terminal such as a smartphone or a vendor server may analyze and display an optimum payment condition containing a minimum payment amount using bonus information such as card information, discount information, membership point information, or coupon information when a user pays, thus preventing personal information leakage and enabling the user to pay a minimum amount by means of his/her credit card using the bonus information.
